How to remove Lock Screen and Logout from the GNOME main menu in SLED11?

Question

I have SLED11 running on some computers that I need to lock down. I specifically need to remove the Lock Screen and Logout options from the main menu (below, on the right side, near the middle) to help me accomplish this.

The SLED11 main menu looks like this:

Trouble is, I've tried using gconf-editor with no success. I've set the following to true:

/apps/panel/global/disable_log_out
/apps/panel/global/disable_lock_screen

I logged out and logged back in, but the main menu still showed Lock Screen and Logout.

How can I remove Lock Screen and Logout from the GNOME main menu in SLED11?

Answer 1

I found that the Lock Screen and Logoff bookmarks are kept in an XML file:

~/.local/share/gnome-main-menu/system-items.xbel

Manually editing this XML file and removing the bookmarks for Lock Screen and Logoff removes them from the main menu--just what I wanted to happen.
